BEx1 valve box

Powered by FESTO and Exepd

The 3 in 1 solution provides plant and machine manufacturers for the first time a decentralized and compact solution with Profinet or Modbus TCP/IP to control pneumatic actuators for hazardous area Zone 1/21

High flow rate in a small space - State-of-the-art bus technology - Unique: The structural design

Tested system solution from

Innovative and compact Ex
IO modules with bus connection

Operationally proven Ex i valve terminal

Certified system installation in Ex e field housing

Applications

  • Paint shops

  • Pharmaceutical plants

  • Chemical plants

  • Tank farm
  • Bulk materials handling systems

  • Mixing / grinding plants

  • Industrial heating / cooling systems

  • Sewage treatment plants and much more

Integration

 

  • The Ethernet connection (Profinet or Modbus TCP/IP)
    is executed in increased safety Ex e.

 

  • Ex media converters or fieldbus couplers in the safe area are not required and the full Ethernet performance can be used.

  • No IO modules required on the PLC

 

  • The BEx1 module does not have to be parameterized or configured and behaves transparently in the control I/O.

 

Installation scheme

Customer benefits

Compact - Simple - Fast

 

  • Central Ethernet connection, central compressed air connection
  • The compact housing enables optimal decentralized installation in the system and guarantees short distances to the sensors and the pneumatic actuators.
  • No compressed air tubing inside the housing.
  • Cost savings and less installation effort

 

The ATEX certified system in the field housing is designed for installation in Zone 1/21

The BEx1 IO valve box combines bus nodes, isolating switching amplifiers, intrinsically safe IO channels and the pneumatic valve terminal.


Functions

  • 8 outputs to 8 valves 3/2 way pre-wired
  • 16 Namur inputs for position feedback
  • 8 DO(AIO)*
    *Individually adjustable as DO, AI, AO or Switching Mode
